The function of car side lights is to help distinguish whether the distance on both sides of the road is suitable for traffic, as well as to determine the distance on both sides of the vehicle when overtaking and passing. Side lights are warning signs installed at the edge of the top of the car, and in rainy, snowy, foggy or other poor visibility situations, they can be used to alert passing vehicles by turning on the wide warning lights.
